Initialize Object Properties

[Shapper]

Hello,

I am injecting in my services a global Settings interface, as Singleton, using StructureMap:

public interface ISettings {
  LoggerSettings Logger { get; }
} // ISettings

public class LoggerSettings {
  public String Levels { get { return ConfigurationManager.AppSettings["Logger.Levels"]; } }
  public const String Report = "te...@xyz.com";
} // LoggerSettings

public class Settings : ISettings {
  public LoggerSettings Logger { get; private set; }
} // Settings

And as SM configuration I have:

For<ISettings>().Singleton().Use<Settings>();

I am able to inject this object but when I check the injected object its property Logger is null ... How can I have SM to initialize the object properties?

Am I missing something?

Thank you,
Miguel

This is still relevant to StructureMap 2.6 (and 3 for that matter):  It wouldn't help you even it was injected because it gets involved before the behavior is pulled from the container.

StructureMap does not do setter injection automatically.  You'll have to explicitly enable setter injection, but in this case it won't work for you because the setter in question is private.

Honestly?  If I were you I'd just inject LoggerSettings directly as a singleton and not worry about anything else.

Yes, that was one of my ideas:

To have a Settings : ISettings with a constructor that takes LoggerSettings, MailerSettings and so on, and initialize the properties.

I would inject LoggerSettings and MailerSettings as Singletons. And Settings also as Singleton in all my services.

But do I need to created interfaces for LoggerSettings and MailerSettings or can I simply use it as follows:

     For<ISettings>().Singleton().Use<Settings>();
    

     For<LoggerSettings>().Singleton().Use<LoggerSettings>();
     For<MailerSettings>().Singleton().Use<MailerSettings>();

I am asking this because it seems to working even if not using interfaces.


A side question: any ETA on StructureMap 3?

Thank You,
Miguel

See the link I meant to send you the first time:  http://docs.structuremap.net/ConstructorAndSetterInjection.htm

Setter injection is NOT a first class citizen in SM and never will be.  It will take you just a bit more effort to enable the setters.

SM 3 ETA?  I had a head of steam, but I'm having to shift to fubumvc & storyteller documentation efforts for a little while.  May/June sounds about right.  Most of the hard work is done though.
